Latest Patents

Yah Leng Lim holds a patent for a "Laser system for imaging and materials analysis." This invention utilizes a THz quantum cascade laser to investigate a target by directing a first beam of laser radiation at it. The interaction between the first beam and the target produces a second beam of laser radiation. The self-mixing of these beams within the laser results in variations in a signal, such as the operating voltage of the laser. By varying an operating parameter that affects the interaction of the first beam with the target, the operating voltage is monitored and processed to determine phase and amplitude changes associated with the material properties of the target. This invention allows for the processing of signal variations to produce various images of the target.
